@ArcticTrestleboard that's just the model failing to call a tool, it should be able to proceed and call it using correct parameters
If u face this a lot consider adding additional instructions for how the llm should call the mcp tools

Going to close since this isn't a bug it is just a tool call validation error being sent back to the llm to tell it it didn't call the tool properly
